The LEBT of the JYFL 14 GHz ECRIS and the configuration of the sector Faraday cup (FC).
Normalized frequency power spectra of the two beam current oscillation “modes.” O6+ beam is used as an example.
Normalized current densities (top) and 2σ-amplitudes of the beam current oscillation (bottom) for O4+–O7+. Ion source is tuned for O6+ in both cases.
An example of typical temporal current signals (normalized) of O5+-O7+ in sectors 1-4, 5-8, and 9-16 combined. The current oscillates at 760 Hz. Sampling rate is set to 250 kHz/channel.
